Contains Duplicate III Given an array of integers, find out whether there are two distinct indices i and j in the array such that the difference between nums[i] and nums[j] is at most t and the difference between i and j is at most k. 关于上述题意,我们可以转化为两…
今天看c++primer第六章,有这部分的内容,脑子有点糊涂了,看了几篇博客,自己敲了下,记录一下备忘. 二级指针: int **p; 二维数组: int p[10][10]; char q[10][10]; 指针数组: int *p[10]; 数组指针: int (*p)[10]; 咋区分后面这俩呢,记住[]的优先级比*高,所以上面写法,p先和后面的[10]结合,也就是p首先是个10个元素的数组,那么前面的int *就是元素类型,也就是存了10个int指针的数组. 那么下面这个写法把 * p括…
Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. For example, Given [3,2,1,5,6,4] and k = 2, return 5. Note: You may assume k is always valid, 1 ≤ k ≤ array'…
